Please review KB IAS-12136 for more detail.
|Virtual Environments||We test our products in virtual environments including PCs (HyperV) and Terminal Services along with virtualised hardware i.e. Server/Terminal Server(s)/configuration clusters. |
To provide optimum performance in a virtualised cluster, our recommended setup is to have the application, SQL and Terminal Server(s) on separate virtual machines.
We do not specifically test against the following virtualised environments. Many customers have however, stated that they use these environments without a problem:
If you do come across an issue, we will try and help you narrow down the area in the virtual environment that is causing the problem but cannot guarantee resolution in any untested platforms.
Remote Access including Terminal Server access
Remote access to PCs, Servers and Terminal Servers are tested via Microsoft’s Remote Desktop Connection on all supported platforms.
|Exchange||Running SQL Server and Exchange on the same server while possible, is not recommended, as it may impact the performance of IRIS Accountancy Suite Software.|
Anti-Virus and Firewall Protection
Some anti-virus software or firewall protection may prevent successful installations of IRIS software. In some cases, the anti-virus or firewall software may need disabling while the installation is running. If you require assistance with this, please contact your anti-virus or firewall software supplier.

IRIS has offered extended support for use of its products with Office 2007 but as we are now over 18 months past this date, this extended support has been terminated.
